The tin' p ate'or other s eets are` stacked on the lay-board from which they are taken l.one at a time an placeda ainst the steel face '.platfes'g of a verticalfeedvcard g-, secured to on the machine-frame. l, The sheet is pushed down the'face-plate until its Ylower edge rests on the arms or lays h, being 'guided into and held in posi-tion thereon by steel springs t and 'srnoothers c. The lsteel springs Si "are preferably mounted to slide a series of rippers e, y
